ubuntu安装opencv

（1）安装编译opencv的环境

sudo apt-get -y install build-essential cmake pkg-config

（2）安装Image I/O库

sudo apt-get -y install libjpeg62-dev

sudo apt-get -y install libtiff4-dev libjasper-dev

（3）安装GTK库

sudo apt-get -y install  libgtk2.-dev

（4）安装Video I/O库

sudo apt-get -y install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev

(5)安装支持摄像头固件的库

sudo apt-get -y install libdc1394--dev

（6）安装视频流库

sudo apt-get -y install libxine-dev libgstreamer0.-dev libgstreamer-plugins-base0.-dev

（7）安装python开发环境和python 数学库

sudo apt-get -y install python-dev python-numpy

（8）安装 Intel tbb library

sudo apt-get -y install libtbb-dev

（9）安装Qt开发库

sudo apt-get -y install libqt4-dev

（10）从http://opencv.org/中下载OpenCV，然后解压缩

tar -zxvf OpenCV-2.9.tar.bz2

创建编译目录

    cd OpenCV-2.9

    mkdir build

    cd build

    cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local

    -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON

    -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON

    -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..

开始编译（这个过程比较长，耐心等待）

 make

最后不要忘记安装

sudo make install

现在配置Qt下OpenCV的开发环境，从http://qt-project.org/下载集成开发环境，安装

然后打开QtCreator，点击File，选择New File or Project，选择Non-Qt Project ,选择Plain C++ Project, 点击choose

项目建立完成后会看到一个*.pro文件然后打开添加OpenCV的库

INCLUDEPATH += /usr/local/include

LIBS += -L/usr/local/lib \

-lopencv_core \

-lopencv_imgproc \

-lopencv_highgui \

-lopencv_ml \

-lopencv_video \

-lopencv_features2d \

-lopencv_calib3d \

-lopencv_objdetect \

-lopencv_contrib \

-lopencv_legacy \

-lopencv_flann

然后就可以写程序了
